Mutable Instruments Blinds
Scale, invert, offset, and mix four signals at once
12 HP Eurorack module
Blinds is a quad VC-polarizer that lets you scale, invert, and offset up to four modulation or audio signals simultaneously. Each channel functions as a VCA, inverter, ring modulator, or CV mixer depending on how it is patched, making it an expressive hub for shaping and combining modulations. Its bipolar gain range and offset capability give it a characterful, musical flexibility rare in utility modules.
Features
- Four independent VC-polarizer channels
- Bipolar gain range of +/-2 per channel
- Linear gain response: +5V CV = gain of 1
- CV offset range of +/-5V per channel
- All inputs DC-coupled and audio-rate capable
- Input impedance of 100k on all inputs
- Can function as VCA, inverter, ring modulator, CV mixer, or offset generator
- LED per channel for visual feedback of signal level and polarity
- 12HP wide, 25mm deep
